Inquiry (采购产品): Paper Loading Tray Hello, I am looking for a device that takes a stack of paper and as sheets are removed from the top, the remainder of the stack moves up in order to maintain the top sheet in the same relative vertical position regardless of how much of the stack remains. Can you help me?
